Brothers in arms
For the Italians playing in their 10th Championship since five became six back in 2000 the Bergamasco brothers have become almost ever-presents since the younger Mirco joined big bruv Mauro in the side in 2002.
Mauro played at open-side flanker in Italy's 34-20 win over Scoland in their first match and this weekend will rival our own Austin Healey as international rugby's Mr Versatile having been chosen at scrum-half to add to his caps in the back row and on the wing.
Meanwhile for the home side Steffon Armitage will make his debut alongside brother Delon - making them the first brothers to represent England since the Underwood boys Rory and Tony in 1995.
As Rory was roaring to his position as England's top try scorer (with 49) there were regular Twickers shots of mum Annie celebrating in the old East Stand. This Saturday watch out for Mrs Verna Armitage and husband John who we are hoping to hear from in the build-up to Saturday's opener.
OK here's your starter for 10. Who were the last pair of brothers to play against each other in the Six Nations? (Answer below)
Mention of Mrs U reminds me of the survey back in 2002 which found that she was more well known to the British public than a certain Jonny Wilkinson. At that time of course England's home games were not broadcast on terrestrial TV as they had been through Rory and Tony's career.
BBC TV coverage on Saturday begins at 1.30pm when there is a chance to see a superb documentary made in BBC Wales looking back at the Welsh Grand Slam of 2008. This uses "The Cut" footage that our extra, low cameras have been capturing at Six Nations games since 2003 and which has proved so popular in showing the pace and power of the professional game.
From 2pm John Inverdale will be live at Twickenham for an extensive build-up to the first match. Watch out for Sonja McLaughlan's first interview with Martin Johnson, interviews with the Armitage brothers and Andy Goode, Johno's surprise selection at fly-half. Also Keith Wood has been speaking to Brian O'Driscoll ahead of a huge season for the last Lions captain ahead of the summer's trip to South Africa.
England v Italy kicks off at 3pm and will be followed on BBC1 by Ireland v France live (KO 5pm). Ireland fans will not want to be reminded of the late, late Vincent Clerc try that ultimately cost them a Grand Slam in this corresponding fixture from 2007 - which was the historic first rugby union international at Croke Park.
On Sunday we are on from 2.25pm on BBC1 as Wales begin their defence of the title against Scotland at Murrayfield. Every year it seems Scotland are put forward as the 'dark horses' for the Championship, but it is worth pointing out that Frank Hadden's team have beaten all five of the other nations within the past three years.
Before this game we'll hear from Lee Byrne, arguably the player of the autumn internationals and Scotland's fly-half Phil Godman - who also takes on the crucial place kicking duties, an area that cost his side dearly against South Africa in November.
As ever there are lots of ways to enjoy the Six Nations experience with the BBC. All of the England, Wales and Scotland home matches are available in High Definition on the HD channel while Radio 5 will have all the team news and discussion in the days ahead of each match. Watch out too for Matt Dawson's preview programme ahead of every weekend of the Championship.
On the Red Button there will be highlights of every match as well as commentary alternatives for all the different nations. Our popular forums will also be back every weekend starting after the Ireland v France match with Gabby Logan on Saturday. Also hit your red button now and go to the sport multiscreen where there are two streams of preview material plus an entertaining historical review entitled the 'Ruck n Roll Years'.
On the BBC Sport website too there will be extended versions of this preview material, match highlights and your chance to select your Lions squad for the summer and see how it compares with our panel of experts - Jonathan Davies, Jeremy Guscott, Andy Nicol and Keith Wood.
Finally if you want to relive any match in full they are available on the BBC iPlayer for up to seven days afterwads.
It promises to be a fascinating seven weeks with the six teams more equally matched than at any time in recent years. Wales are the bookies favourites at about 2-1 and would probably carry my fiver too if pushed.
Let's hope the weather clears up around our three venues for this weekend. And I recommend you stay indoors for what should be a cracking start to the tournament.
*The last time brothers played against each other in the Six Nations was actually only two years ago when Rory and Simon Best of Ireland came up against the Lamont brothers of Scotland - Rory and Sean.
